COMMENT: Seedpod looks like a green bean. Delicious roots. “They can be dug any time of year, and are usually just under the surface... They’re like beads on a string except they are larger and farther spread out.  The “string” can also branch off. To find them I look for the vine climbing bushes and trees. It’s thin, about an eight of an inch through, covered with fine hair, and tough for its size… Groundnuts have a bitter latex in them and should be cooked first. They also have some “anti-nutrition factors” including protease inhibitors which cooking neutralizes… Groundnuts can be pea size to baseball size, smooth or lumpy. Most of the ones I find look like dark brown lumpy eggs. First year groundnuts are light yellow to reddish brown, and small. Second year, larger, darker, coarser. All are edible and peel like a tough potato.”

 

CAUTION: 1% of population allergic. Avoid if you have a peanut allergy.

 

NUTRITION/MEDICINAL: Groundnut also contains genistein, a known anti-carcinogenic compound. The Indians made a plaster out of it (cooked) for external cancers.(2) Tubers contain 17% crude protein, this is more than 3 times that found in potatoes. The tubers can be harvested in their first year but they take 2 - 3 years to become a sizeable crop. (1)
